Analyte concentration alert function for analyte sensor system
Systems, methods, and apparatuses that provide alerts based on analyte data and acceleration data. An analyte sensor may generate the analyte data. An accelerometer may generate the acceleration data. A transceiver may convert the analyte data into analyte concentration values. The transceiver may convert the acceleration data into activity information. The transceiver may generate an alert based on the analyte concentration values and activity information. The alert may be communicated to a user by a mobile medical application executed on the transceiver and/or a display device (e.g., smartphone) in communication with the transceiver. The mobile medical application may display (e.g., on a display of the display device) a plot or graph of the analyte concentration values and activity information with respect to time.
1. An apparatus comprising:
a sensor interface device configured to receive data signals from an analyte sensor;
an accelerometer configured to generate acceleration data corresponding to movement of the accelerometer; and
circuitry configured to
generate analyte concentration values based on the received data signals;
generate activity information based on the acceleration data by:
converting the acceleration data into scalar acceleration values,
comparing the scalar acceleration values to an activity threshold, and
generating the activity information based on the frequency of scalar acceleration values that exceed the activity threshold; and
generate an alert based on the analyte concentration values and the activity information.
2. The apparatus of claim 1 , wherein the alert is indicative of a current or projected physiological condition or reaction.
